Discussion about the Korg PolySix synthesizer

Hi -
thanks;  had a few minutes last night -- disconnected the wheels from 
the front panel (no help); disconnected CN06 - 2 (no help);  
disconnected R9 that feeds the CV mixer IC 8 :  problem vanished.

Didn't have any more time (dealing with a dead Prophet 5 power 
supply), but it's aroused my curiosity:  why would pulling R9 do the 
job, when pulling CN06-2 had no effect? -- according to the 
schematic, it would be basically the same thing.

Hope to have more time tonight;  meanwhile, any further thoughts 
would be appreciated.

Thanks again.
